Modelling cortical reorganizations in patients with visual field deficits

Période :   au

The aim of the internship is to develop computational models of cortical reorganizations in patients with visual field deficits


A M2 fellowship is available to work at the CerCo laboratory under the supervision of Benoit Cottereau (CNRS research director) and Timothée Masquelier (CNRS research director). The aim of the project is to develop computational models that explain how the visual system evolves following the onset of pathologies associated with visual field deficits (e.g., in patients with macular degeneration or retinis pigmentosa). We will be specifically interested in the neuroplasticity mechanisms that may underly the visual rehabilitations observed in some animal models of these pathologies (see e.g., Shao et al., 2014; Burnat et al., 2017). It will be realized using artificial neural networks (and in particular spiking neural networks) trained with occluded images and/or videos (see e.g., Moore et al., 2021). The outputs of the networks after training will be compared to those observed in neural recordings and/or in behavioural experiments realized in patients (the CerCo has a privileged connection with the Retina Center of the Purpan hospital in Toulouse).

Profil recherché

The candidates should be willing to work in a multidisciplinary environment which combines neurosciences, ophthalmology and AI, have a good level in English with very good programming skills. Some knowledge in neurosciences/ cognitive sciences would be a plus.

Établissement d'accueil

The research will take place at the Cerco laboratory (CNRS UMR 5549 in Toulouse) in the SV3M ( and NeuroAI ( teams. Toulouse is a student city (Toulouse is the second university hub in France) with high quality of life located in the south west of France (close to the Pyrenees, the Mediterranean Sea and the Spanish border).
